表之间的Laravel关系

Question

I have generate the following database table and need to create model form them.

Creating a model seems to be an easy task, but I am confused how should i define the relationship between two tables. In users table RoleId is foreign key. My question is where and how should I define the relationship (in User model or Role model). Should I use hasOne , hasMany , or belongsTo

Answer 1

In your User model

public function roles()
{
    return $this->hasOne('Role', 'id', 'RoleId');
}

In your Role model

public function users()
{
    return $this->belongsTo('User', 'RoleId', 'id);
}
